(Cl. S12-7) 4 Claims.

, 1 In radio receiving sets having self-contained loop antennae thathave directional properties,

Vthe set manufacturers recommend, once the station is tuned in, that thecabinet be rotated on its base back and forth through a quarter of acircle, and left at the position where the desired station is receivedwith maximum volume.

The principal object of the present invention is to provide means whichis simple in construction and convenient in use for thus rotating thecabinet of a radio receiving set.

Another of the objects of the invention is to provide novel and improvedmeans of the character indicated.

The invention is illustrated, by way of example. in the acconpanyingdrawings, in which:

Figure 1 is a front elevation of a radio receiving set embodying thefeatures of the invention in their preferred form;

Fig. 2 is a detail sectional elevation, on an enlarged scale, taken onthe line 2-2 of Fig. i, certain parts being removed from the interior ofthe set for the sake of clearness;

Fig. 3 is a similar view but with certain operating parts shown insection; and

Fig. 4 is a detail sectional plan view taken substantially on the line4-4 of Fig. 3.

The radio receiving set illustrated in the drawings is provided with theusual cabinet 2 having a bottom wall or base l, supporting members l,dial 8, control knobs I0, and amplifier I2.

In accordance with the present invention, there is provided asupplemental support il which comprises a disk that is rotatably mountedon the lower end of a post i8. The disk is thus mounted on the post bymeans of a screw Il which extends loosely through an aperture in thedisk and is screw-threaded into the lower end of the post It. andwashers at opposite sides of the disk. The

underside of the supplemental disk has a cutaway portion 22 whichreceives the lower end of the screw i8 and the lower washer 2l, so thatthese parts do not project below the bottom surface of the disk.

The upper portion of the post i8 telescopes into a tubular bracketmember 2l, the upper end of which is provided with a flange 2i whichissecured by screws 28 to the underside of a, partition 30 in thecabinet.

The upper part of the post I6 is provided with rack teeth 32 which areoperatively engaged by a pinion 24 which extends through apertures inthe tubular member 2l, the pinion being formed on a shaft 3B. A washer36 is secured by a screw to one end of the pinion Il, and isfrictionally held against the side of the tubular member 2| by means ofa spring I0 coiled about the pinion and interposed between the tubularmember 34 and a lcollar Il on the shaft II, thus preventing looseness ofparts. The shaft 3l extends outwardly through an aperture in the frontwall of the cabinet and has secured on the outer end thereof anoperating knob 4l;

Normally the supplemental support Il is received in a recess '40 in theunderside of the bottom wall or base I of the cabinet, and when thesupplemental support is in this position the cabinet rests on thesupporting members 6.

When it is desired to use the supplemental support il, the knob Il isturned in a clockwise direction which through the pinion 3l and the rack32 moves the post il downwardly until the supplemental support engagesthe table or other support upon which the cabinet rests, and then duringthe continued movement of the knob the cabinet is raised sufficiently tocause the members 6 to be free of the table, and the cabinet to besupported by the supplemental support. When the cabinet is thus raisedinto this position, it is held from downward movement by the action ofthe spring J8. the inner end I! of which engages a tooth of the pinionIl and there is suilicient play between the pinion and the walls of theapertures in the tubular member 24 to cause the pinion to bind againstthe walls of the apertures and thus hold the pinion from turning.

It will be noted that when the cabinet is thus supported by thesupplemental support Il, it may be easily and conveniently turned backand forth and left in the position where the desired station is receivedwith maximum volume.

The cabinet may be lowered and said support received in the recess 4I byturning the knob Il in a counter-clockwise direction, the support beingheld in the position thus moved by the binding action above described ofthe spring 38. When the supplemental support is thus retracted thecabinet again rests on the members 6, and the supplemental support isout of the way so as not to interfere while the set is being carriedfrom place to place or packed for shipment.

It will be apparent that my improved device is simplein construction andconvenient in use, and that it is particularly adapted for the cabinetsof radio receiving sets of the character indicated.

' What I claim is:

l. The combination of a cabinet provided with a bottom wall having arecess in the underside thereof, the cabinet being normally supported bysaid bottom wall, a supplemental support rotatably connected with thecabinet and normally received in said recess, a manually operablemember, means operable by said member for raising and lowering thecabinet with relation to said supplemental support to cause the cabinetto be respectively supported by said support and bottom wall, and meanscooperating with said member and said rst mentioned means formaintaining the cabinet in a desired position Awith relation to saidsupport when said member is released.

2. In a radio receiving set having a cabinet provided with asupportingbase, a supplemental support arranged beneath the cabinet and rotatablyconnected therewith, a member manually zol the upper member with saidcabinet, a manually operable member, a device operable by said memberfor relatively moving said telescoping members axially to raise andlower the cabinet with relation to said supplemental support to causethe cabinet to be respectively supported by said supplemental supportand said base, and means oooperating with said device tor maintainingthe cabinet ina desired position with relation to said support when saidmember is released.y

i. A structurev according to claim 3 in which the means for relativelymoving the telescoping members axially comprises a rack carried by oneof said members, and a pinion operatively engaging said rack androtatable in opposite directions by means of said manually operablemember.
